5D1F87D2FFFD1A2B8BDFFE7CFB06C7C6.taxon	diagnosis	Differential diagnosis. The new species is most similar to A. similis Khaustov and Frolov, 2019 by the absence of setae chb, presence normally of three pairs of aggenital setae, tectal setae on tarsi II-IV not modified, and setae c 1 well developed. The new species differs from A. similis by the absence of setae or alveolus sc 1 (vs. microseta sc 1 present in A. similis), absence of cupules ih (vs. present in A. similis), and by pointed setae ag 1 (vs. setae ag 1 distinctly blunt-ended in A. similis).	en	Khaustov, Alexander A., Frolov, Andrey V.
